It's more because the ISP can now charge tolls in both directions, so prices for streaming services will hike up.

This effectively allows the ISP to sell their one pipe to the internet twice. They can go to YouTube and Netflix and say, "You haven't paid us to send your content down your pipes." Meanwhile saying to the consumer "You need to pay us so you can get access to the internet."

So, some ISP's will still allow access to the internet. While others will allow access, to what I call, the interNOT.

Edited to add:

I suspect that someday someone will come up with some legislation that says if you don't have access to the full internet, then an ISP can't call it "internet service". Because it's not.
